Sorbead India is well known for its high-quality absorbers and desiccants. Its Desiccant pillow packs consist of a wide variety of sizes, configurations, and substrates. These can be used to absorb moisture vapor, odor and gas according to your desire. We also provide custom blends that can be used as a multifunction package. The multi-function packs absorb two or more unwanted substances from the container.  They are available in a wide range of different sizes of ¼, ½, ¾, 1, 1 ½, 2, 3, 4, 5, 7, 10, 12 or 14 grams. The different materials used for desiccant material silica gel, indicating silica gel, clay, molecular sieve and carbon packed in Tyvek, non-woven or clear view desiccant Packs.

They are used to absorb moisture from 1 gallon can or 10-gallon containers. Desiccant pillow packs are used in pharmaceutical, electronics, diagnostic kits, foods, clothing, powders, vitamins, consumer products, and parts industries to extend the shelf life of the products by absorbing all the moisture and keeping a balance in humidity. Our pillow packs meet FDA and USDA standards and are used in a variety of package applications. These desiccant pouches are also used for the dehumidifier process using a molecular sieve and silica gel packets.

We are prominent manufacturers, suppliers, and exporters of superior quality desiccant pillow packs. These pillow packs are ideal for use in both industries and households for protection from moisture. Desiccant Pillow Pack supplied as per the international standards USFDA ensures high durability and good quality. They have high absorbent capacity for humidity and easily protect containers from moisture damage while goods are in transit. They are also environment-friendly, non-corrosive, and non-toxic and can be disposed of off like any normal waste when removed from containers and boxes after full use.

Desiccants protect your pharmaceuticals by reducing air humidity. Thus, a barrier layer is needed to limit the air exchange. Desiccants come in various forms and have found its important place in the packaging of various pharmaceuticals.

Before selecting the type of desiccant, calculating the correct amount of desiccant is important for maintaining the efficacy of the product and it depends on the following parameters:

• Identifying the type of container. It differs for flexible (eg: foil or polybag) and rigid type (eg: drum or pail)
• Calculating the surface area of the container walls in ft 2 or in 2 for flexible; or the volume of the container in gal., ft3 or in3 for rigid.
• Adsorption rate and adsorption capacity of the desiccants being used.
• A number of units required also differs for flexible containers and rigid containers.

Types of Pharmaceutical Desiccants:

Silica Gel Sachet /Packet

It contains silica gel made from amorphous sodium silicate that is highly absorptive in nature or composition. It absorbs 40% of its own weight and is highly absorbing material unlike others in the market. It is hard, translucent material with an extremely high capacity for moisture at temperatures below 75? F and humidity levels above 40 percent. It is characterized by stable properties, non-toxicity, excellent moisture absorption performance and does not affect any products it comes in contact with. It is especially suitable for the moisture-proof packaging in the pharmaceuticals.

Activated Carbon Sachet /Packet

Activated carbon used in controlling objectionable odors and gases through the process of adsorption.  Activated carbon has been used extensively for many years as an adsorbent of odors and toxic gasses and it performs unmatchable functions when it comes to adsorption of odours.

Molecular Sieve Sachet /Packet

Molecular sieve is a very aggressive desiccant that can be used to quickly absorb moisture and odor. Molecular sieves are alumino silicates, a crystalline porous solid with a three-dimensional network with different pore sizes (3-5 Å). They have to be activated prior use and also can be regenerated at higher temperatures (180 oC - 260 oC) .It comes in the form of beads which has specific pore sizes.

Clay Desiccant Sachet /Packet

Montmorillonite clay is a naturally occurring adsorbent created by the controlled drying of magnesium aluminum silicate. It is a free-flowing granular material with high moisture adsorbing ability from 20 to 80 percent relative humidity under normal packaging and storage conditions.

An important factor that adds to the efficiency of any desiccant is the cover stock, which means material used for its packaging. The cover stock must allow the desiccant to perform its functions without causing any harm to the product. The cover stock allows the desiccant to maintain an acceptable adsorption rate. One common cover stock used widely is Tyvek, a spunbonded, high-density, polyethylene.

Hence, one should always be mindful of all the characteristics of the desiccants and material used in its packaging as well as the packaging of pharmaceuticals. All these parameters are specific to the desiccants in question and therefore are important for the consideration in order to obtain the desired results.
